Curriculum vitae PhD Laura Ewell

Research Interests

We strive to understand how the unique properties of individual neurons support complex behaviors and pathology. We study the hippocampus, a brain structure crucial for memory and also strikingly vulnerable to pathologies.


We use in vitro electrophysiology to study individual neurons and microcircuits and in vivo electrophysiology to study networks during behavior.
